UNITED STATES JUSTIN A. ELIAS, OF PHILADELPHIA, PENNSYLVANIA;

PAPER FASTENER.

Application filed November 16, 1923, Serial No. 675,048. RenewedDecember 19, 1925.

T0 aZZ whom it may concern:

Be it known that I, JUs'riN A. ELIAS, a citizen of the United States,residing in the city and county of Philadelphia, State of Pennsylvania,have invented a certain new and useful Paper Fastener, of which thefollowing is a specification.

This invention, generally state-d, relates to a hinder or fastener forsheets of paper, drawings, tracings, blue prints, andthc like, and hasmore particular relation to a locking arrangement therefor.

Engineers, draughtsmen, architects, contractors and others, atpresentexperience considerable dirhculty with paper fasteners forseveral reasons, chief among which mention may be made of the followingz- With certain types of fasteners it has been found that the weight ofplurality of sheets has the tendency to displace fastener parts whichcauses the sheets to be unsecurely held together. In other types it isnecessary to have a device for forming apertures to receive a' pair ofspaced fastener prongs or tongues. In still other types it is necessaryto bend overa multiplicity of lugs or the like before the sheets can bedisengaged.

The leading object of the present invention is to overcome the aboverecited disadvantageous fcatures and provide a paper fastener which-maybe attached to a series of sheets without punching more than a singleaperture; which when in position securely holds the sheets in properposition without regard to weight thereof; and which may be readilyopened to permit of removal of one or more sheets. Other and furtherobjects reside in the provision of general details of construction andarrangement and combination of parts for attaining the results sought insaid leading object.

The invention consists of the features hereinafter described and finallyclaimed.

The nature, characteristic features and scope of the invention will bemore fully undcrstood from the following description taken in connectionwith the accompanying drawings forming part hereof and in which:

Figure 1, is a perspective view of a paper fastener embodying theinvention about to be fitted to place with respect to a plurality ofsheets of paper or the like.

Figure 3, is a similar view showing the fastener in secured position.

Figure 3, is a. fragmentary sectional view taken upon the line 3-3 ofFigure 2, and

Figure 1, is a view of a fastener part as stamped fro-m a blank. 7

For the purpose of illustrating my invention I have shown in theaccompanying drawings one form thereof which is at Referring to thedrawings in detailand first to Figure 4', there shown afastener part asstamped from a blank. In practice, thin pliable metal, as brass is used.The fastener part as stamped is substantially I- shaped with a single,central perforation 10 in the narrow bodypart 11. The opposed ends 1212are of greater width than the body and the outer edges of each end arebent overtoward each other so as to meet at a'line passinglongitudinally through the center of saidbody. There are thus providedkeepers 13 as clearly shown in Figure 1. The body portion is then bentover so that the two keepers are arranged in parallelism. It is in thisform that the fastener part is sold to the trade, with or withoutpin-clips 14, best seen in Figure 3. In practice a plurality of sheetsof paper 15, or other desired material, is provided with a singleperforation 16 through which is inserted a conventional paper-clip 14,see Figure 1. my novel fastener part is then caused to engage over theprongs of said clip and to further engage within the keepers 13, theprongs in practice being sufficiently long to project entirely throughthe keepers. In this position the fastener part ends together with theprongs ofthe paper clip therein are flattened out upon the uppermostsheet as clearly shown in Figs. 2 and 3. Thus the head of the papenclipin one instance and the overturned or flattened fastener parts in theother instance serves to clamp securely therebetween said sheets. Notonly are sheets 15 thus firmly bound in place againstaccidentaldisplacement. but should it be necessary to remove a sheet or so it ismerely necessary to bend upwardly the keepers and lift them'from thepaper clip whereupon The apertured body portion of ready access may behad to sheet or sheets desired- The paper-clips are made in various butstandard sizes and the fastener of the invention is made in sizes foruse in conjunction therewith.

It will now be apparent that I have devised a novel and usefulconstruction which embodies the features of advantage enumerated asdesirable in the statement of the invention and the above descriptionand while I have in the present instance shown and described thepreferred embodiment thereof which has been found in practice to givesatisfactory and reliable results, it is. to be understood that the sameis susceptible of modification in various particulars Without departingfrom the spirit or scope of the invention or sacrificing any of itsadvantages.

Having thus described my inventiomwhat I claim as new and desire tosecure by Letters Patent, is

- 1. As an article of'manufacture, a fas tener for sheet bindingcomprising abody having a single opening for pliable binding tongue'penetrat1on,' and having parallel lzeeper portions each of which isadapted to receive a prong of the binding tongue and capable of beingfolded to flat, opposed position with the prongs therein.

2. A binding device comprising a paperclip having a pair of pliableprongsfor passage through a single opening in sheets to be bound, afastener the body of which has a single opening for penetration of said)ron s, and iarallel keeers for said bod signed my name.
